From this site comes this picture of handmade costumes inspired by the film Earth vs. The Saucermen:
The article comes complete with detailed descriptions of making the costumes. YOU could be a sci-fi classic character this Halloween!
And even better, the article describes the comedic dance routine these Saucermen were part of at a convention. The routine was based on a scene in another classic movie that you never in a million years would associate with Earth vs. The Saucermen.
